QComboBox - how to click on QStandardItem?

TomNow99

Hello,

I try to create QComboBox with checkBoxes. Now I have QComboBox, and add to it QStandardItems.

my code:

void myComboBox::addItem(const QString &text)
{
    int row = model->rowCount();
    QStandardItem* item = new QStandardItem();
    item->setText(text);
    item->setFlags(Qt::ItemIsUserCheckable | Qt::ItemIsEnabled);
    item->setData(Qt::Unchecked, Qt::CheckStateRole);
    model->setItem(row, 0, item);
    this->setModel(model);
}

When I click on red area everything is ok - I can checked and unchecked the item. But when I click on green area there is no effect.

Goal: When I click on item in green area I would like to checked or unchecked his red area square and don't close comboBox ( because this is combobox with checkBoxes, so user maybe want to select more items ).

I try QComboBox' s signals but there is no effect.

EDIT:
I add:

item->setSelectable(true);

and signal

QComboBox::activated

Now I can click on green area and change his checked/unchecked square ( red area ). But the problem is when I clicked on any item I close QComboBox too…

EDIT 2:
I add to slot to signal QComboBox::activated

myComboBox::showPopup();

This is good, but I see that qcombobox is close and next is open. So must be better solution

EDIT 3:
I find solution:
